THIRD LIEN GUARANTY

This THIRD LIEN GUARANTY (this Guaranty )is entered into as of October 9, 2008 by the undersigned (each a Guarantor , and together with any future Subsidiaries of Company executing this Guaranty, being collectively referred to herein as the Guarantors ) in favor of and for the benefit of The Bank of New York Mellon, as Collateral Agent for and representative of (in such capacity, together with its successors and assigns herein called Guarantied Party ) the holders of the Notes (as defined in the Purchase Agreement referred to below) (sometimes referred to as Holders or Beneficiaries ) issued pursuant to that certain Third Lien Subordinated Exchange Note Exchange Agreement dated as of the date hereof (as it may be amended, supplemented or otherwise modified from time to time, the Exchange Agreement ; capitalized terms defined therein and not otherwise defined herein being used herein as therein defined) by and among NextWave Wireless Inc., a Delaware corporation ( Parent Issuer ), NextWave Wireless LLC, a Delaware limited liability company ( Company ), the Subsidiaries of Company from time to time party thereto, the Purchasers named therein and the Guarantied Party, as Collateral Agent.

WHEREAS , it is a condition precedent to the issuance of the Notes under the Exchange Agreement that Parent Issuers obligations under the Note Documents be guarantied by Guarantors;

WHEREAS , Guarantors are willing irrevocably and unconditionally to guaranty such obligations of Parent Issuer.

NOW, THEREFORE, based upon the foregoing and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and in order to induce the Purchasers to enter into the Exchange Agreement and purchase the Notes, Guarantors hereby agree as follows:

1.           Guaranty. (a) Guarantors jointly and severally irrevocably and unconditionally guaranty, as primary obligors and not merely as sureties, the due and punctual payment in full of all Guarantied Obligations (as hereinafter defined) when the same shall become due, whether at stated maturity, by acceleration, demand or otherwise (including amounts that would become due but for the operation of the automatic stay under Section 362(a) of the Bankruptcy Code). The term Guarantied Obligations is used herein in its most comprehensive sense and includes any and all obligations of Parent Issuer in respect of notes, advances, borrowings, loans, debts, interest, fees, costs, expenses (including, without limitation, legal fees), indemnities and liabilities of whatsoever nature, now or hereafter made, incurred or created, whether absolute or contingent, liquidated or unliquidated, whether due or not due, and however arising under or in connection with the Exchange Agreement, the Notes, this Guaranty and the other Note Documents.

Each Guarantor acknowledges that a portion of the proceeds of the Notes may be advanced to it and that the Guarantied Obligations are being incurred for and will inure to its benefit.

Any interest on any portion of the Guarantied Obligations that accrues after the commencement of any proceeding, voluntary or involuntary, involving the bankruptcy, insolvency, receivership, reorganization, liquidation or arrangement of Parent Issuer (or, if interest on any portion of the Guarantied Obligations ceases to accrue by operation of law by reason of the commencement of said proceeding, such interest as would have accrued on such portion of the Guarantied Obligations if said proceeding had not been commenced) shall be included in the Guarantied Obligations because it is the intention of each Guarantor and Guarantied Party that the Guarantied Obligations should be determined without regard to any rule of law or order that may relieve Parent Issuer of any portion of such Guarantied Obligations.

In the event that all or any portion of the Guarantied Obligations is paid by Parent Issuer, the obligations of each Guarantor hereunder shall continue and remain in full force and effect or be reinstated, as the case may be, in the event that all or any part of such payment(s) is rescinded or recovered directly or indirectly from Guarantied Party or any other Beneficiary as a preference, fraudulent transfer or otherwise, and any such payments that are so rescinded or recovered shall constitute Guarantied Obligations.

Subject to the other provisions of this Section 1, upon the failure of Parent Issuer to pay any of the Guarantied Obligations when and as the same shall become due, each Guarantor will upon demand pay, or cause to be paid, in cash, to Guarantied Party for the ratable benefit of Beneficiaries, an amount equal to the aggregate of the unpaid Guarantied Obligations.

(b)       Anything contained in this Guaranty to the contrary notwithstanding, the obligations of each Guarantor under this Guaranty and the other Note Documents shall be limited to a maximum aggregate amount equal to the largest amount that would not render its obligations hereunder subject to avoidance as a fraudulent transfer or conveyance under Section 548 of Title 11 of the United States Code or any applicable provisions of comparable state law (collectively, the Fraudulent Transfer Laws ), in each case after giving effect to all other liabilities of such Guarantor, contingent or otherwise, that are relevant under the Fraudulent Transfer Laws (specifically excluding, however, any liabilities of such Guarantor (x) in respect of intercompany indebtedness to Parent Issuer or other affiliates of Parent Issuer to the extent that such indebtedness would be discharged in an amount equal to the amount paid by such Guarantor hereunder and (y) under any guaranty of subordinated Indebtedness which guaranty contains a limitation as to maximum amount similar to that set forth in this Section 1(b), pursuant to which the liability of such Guarantor hereunder is included in the liabilities taken into account in determining such maximum amount) and after giving effect as assets to the value (as determined under the applicable provisions of the Fraudulent Transfer Laws) of any rights to subrogation, reimbursement, indemnification or contribution of such Guarantor pursuant to applicable law or pursuant to the terms of any agreement.

(c)       Each Guarantor under this Guaranty, and each guarantor under any other guaranties of the Obligations of the Parent Issuer under the Exchange Agreement and the Notes (the Related Guaranties ) that contain a contribution provision similar to that set forth in this Section 1(c), together desire to allocate among themselves (collectively, the Contributing Guarantors ), in a fair and equitable manner, their obligations arising under this Guaranty and the Related Guaranties. Accordingly, in the event any payment or distribution is made on any date by a Guarantor under this Guaranty or a guarantor under a Related Guaranty, each such Guarantor or such other guarantor shall be entitled to a contribution from each of the other Contributing Guarantors in the maximum amount permitted by law so as to maximize the aggregate amount of the Guarantied Obligations paid to Beneficiaries.

2.           Guaranty Absolute; Continuing Guaranty. The obligations of each Guarantor hereunder are irrevocable, absolute, independent and unconditional and shall not be affected by any circumstance which constitutes a legal or equitable discharge of a guarantor or surety other than payment in full of the Guarantied Obligations. In furtherance of the foregoing and without limiting the generality thereof, each Guarantor agrees that: (a) this Guaranty is a guaranty of payment when due and not of collectibility; (b) Guarantied Party may enforce this Guaranty upon the occurrence and during the continuance of an Event of Default under the Exchange Agreement; (c) the obligations of each Guarantor hereunder are independent of the obligations of Parent Issuer under the Note Documents and the obligations of any other guarantor of obligations of Parent Issuer and a separate action or actions may be brought and prosecuted against each Guarantor whether or not any action is brought against Parent Issuer or any of such other guarantors and whether or not Parent Issuer is joined in any such action or actions; and (d) a payment of a portion, but not all, of the Guarantied Obligations by one or more Guarantors shall in no way limit, affect, modify or abridge the liability of such or any other Guarantor for any portion of the Guarantied Obligations that has not been paid. This Guaranty is a continuing guaranty and shall be binding upon each Guarantor and its successors and assigns, and each Guarantor irrevocably waives any right (including, without limitation, any such right arising

under New York Civil Code Section 2815) to revoke this Guaranty as to future transactions giving rise to any Guarantied Obligations.

3.           Actions by Beneficiaries. Any Beneficiary may from time to time, without notice or demand and without affecting the validity or enforceability of this Guaranty or giving rise to any limitation, impairment or discharge of any Guarantors liability hereunder, (a) renew, extend, accelerate or otherwise change the time, place, manner or terms of payment of the Guarantied Obligations, (b) settle, compromise, release or discharge, or accept or refuse any offer of performance with respect to, or substitutions for, the Guarantied Obligations or any agreement relating thereto and/or subordinate the payment of the same to the payment of any other obligations, (c) request and accept other guaranties of the Guarantied Obligations and take and hold security for the payment of this Guaranty or the Guarantied Obligations, (d) release, exchange, compromise, subordinate or modify, with or without consideration, any security for payment of the Guarantied Obligations, any other guaranties of the Guarantied Obligations, or any other obligation of any Person with respect to the Guarantied Obligations, (e) enforce and apply any security now or hereafter held by or for the benefit of any Beneficiary in respect of this Guaranty or the Guarantied Obligations and direct the order or manner of sale thereof, or exercise any other right or remedy that Guarantied Party or the other Beneficiaries, or any of them, may have against any such security, consistent with the Exchange Agreement and the Note Documents, including, any applicable security agreement, including foreclosure on any such security pursuant to one or more judicial or nonjudicial sales, whether or not every aspect of any such sale is commercially reasonable, and (f) exercise any other rights available to Guarantied Party or the other Beneficiaries, or any of them, under the Note Documents.

4.           No Discharge. This Guaranty and the obligations of Guarantors hereunder shall be valid and enforceable and shall not be subject to any limitation, impairment or discharge for any reason (other than payment in full of the Guarantied Obligations), including without limitation the occurrence of any of the following, whether or not any Guarantor shall have had notice or knowledge of any of them: (a) any failure to assert or enforce or agreement not to assert or enforce, or the stay or enjoining, by order of court, by operation of law or otherwise, of the exercise or enforcement of, any claim or demand or any right, power or remedy with respect to the Guarantied Obligations or any agreement relating thereto, or with respect to any other guaranty of or security for the payment of the Guarantied Obligations, (b) any waiver or modification of, or any consent to departure from, any of the terms or provisions of the Exchange Agreement, the Notes, any of the other Note Documents or any agreement or instrument executed pursuant thereto, or of any other guaranty or security for the Guarantied Obligations, (c) any agreement relating to the Guarantied Obligations at any time being found to be illegal, invalid or unenforceable in any respect, (d) the application of payments received from any source to the payment of indebtedness other than the Guarantied Obligations, even though Guarantied Party or the other Beneficiaries, or any of them, might have elected to apply such payment to any part or all of the Guarantied Obligations, (e) any failure to perfect or continue perfection of a security interest in any collateral which secures any of the Guarantied Obligations, (f) any defenses, set-offs or counterclaims which Parent Issuer may assert against Guarantied Party or any Beneficiary in respect of the Guarantied Obligations, including but not limited to failure of consideration, breach of warranty, payment, statute of frauds, statute of limitations, accord and satisfaction and usury, and (g) any other act or thing or omission, or delay

to do any other act or thing, which may or might in any manner or to any extent vary the risk of a Guarantor as an obligor in respect of the Guarantied Obligations.
